The Use of a Floating Electromagnetic Level Gauge in Surface Oil Tanks

A level gauge for measuring the level of oil in vertical surface tanks, which is highly reliable and accurate and has a comparatively simple construction, is described. The construction of the electric circuit of the level gauge and data of an experimental structure and its accuracy characteristics are presented.__________Translated from Izmeritel’naya Tekhnika, No. 5, pp. 43–47, May, 2005.     

Modernization of the UKh-2 Chlorine Level Meters

An improved construction of the UKh-2 level meter is described, in which a new sensor inductance coil circuit is employed, which enables the unmeasurable layer of liquid at the bottom of the container to be reduced. The main constructional features and electric circuit of the level meter are given, and its fundamental technical characteristics are presented.     

Floating level gauge for liquid chlorine

A new construction is provided for a liquid chlorine level gauge in which the float has the shape of a sphere and the inductance coil of the sensor is made as a differentially-transformed stepped-section scheme that makes it possible to reduce the unmeasured band to the bottom of the vessel.Translated from Izmeritelnaya Tekhnika, No. 12, pp. 48–51, December, 2004.This revised version was published online in April 2005 with a corrected cover date.     

Industrial production of coke briquets for cupola smelting of iron

The benefits of coke-briquet production are outlined. The characteristics of the briquets are noted. The results of their use as fuel in cupola smelting of iron are considered.     

Displacement Transducers

A differential-transformer transducer for large displacements is described. It is made using sectional uniform and stepped windings with resistors so as to provide an extension of the measurement range with a moving element of very small length. An approach is considered to determining the equations of the output characteristics of two versions of the transducer which can be used for calculation and design.
